Suggestions for a new Digital Scale

Scales can be affected by HVAC registers or nearby fans blowing air. Whenever I use my scale(I use a PACT) that is one thing I’m always conscious about. The instructions with my PACT scale say, and it is easy to miss, is once it is turned on it needs time to settle. I noticed one time while reloading I went in for dinner and came out and I had a bullet placed on the scale. When I had left it was reading at 168.3 grains, and it still was showing that. But initially when I started my reloading session I found myself hitting that TARE button because it would keep fluctuating non stop, then tell me to hit TARE. I’m almost positive it was because after I turned it on I went straight to calibrating it and then straight onto weighing ammo, with no time to let it settle.
